. ROLLER FOR WASHING OR DYEING MACHINES.

v SPECIFICATION' forming-part of Letters Patent No. 379,442, dated Iarch13, 1888.

Application filed May 24, 1857. Serial No. 23.9205. (No model.) Patentedin England February 5, 1887, No. 1,833.

To all whom, it may concern:

Be it 1known that I, WILLIAM BIRCH, a subject of the Queen of GreatBritain, and residing at Lower Broughton, Manchester, in t-he county ofLancaster, England, have invented Improvements in Rollers Used inVfashing, Soaping, Dyeing, and other Similar Machines, (for which I haveapplied for .Letters Patent in Great Britain, N o. 1,833,datedFebruary', 1887,) of which the following isa specification.

The object of my invention is to produce a roller having a cellularsurface so formedthat when such roller is i1nn1ersed,either partially orwliolly,in any liquid and a woven fabric is passed round it, so as tocause it to revolve, the tension of the fabric will cause the liquidadmitted to the cells at one part of its revolution to be forced outwardthrough the faloric as those cells come round to another point in therevolution ofthe roller.

According to a former invention of mine, for

which I obtained Letters Patentin the United- States of America, datedJune 22, 1886, No. 844,238, I proposed to make the walls of the cells ofindia-rubber or other collapsible substance; but according to my presentinvention I obtain the same result in a more efficacious manner, and atthe same time I am enabled to employ metal, wood, or other rigidmaterials which are not injuriously affected by the hot or acid liquorsemployed.

Such being the nature and object of my said invention, the manner inwhich the same is to be performed or carried into practical effect willbe readily understood ou reference to the three annexed sheets ofdrawings and the following explanation thereof. y

Figurel is an elevation of one end of a cellular roller constructedaccording to my invention. Fig. 2 is a transverse section of the same,and Fig. 3 a partial longitudinal section thereof with the end plateremoved. Fig. 4 is an end View, also with the end plate removed; andFig. 5 is an inside view of the said plate. Fig. 6 is a transversesection of a modification, hereinafter described.

For the purposes of my invention I take a roller, of wood or othersuitable solid material, a a., which may, if preferred, be covered withsheetcopper or other suitable metal or substance, and I form therein aseries of external longitudinal grooves or recesses, b b, at suitabledistances apart-say about one inch, (more or less.) In these grooves orrecesses?) b, I place-a series of bars, rods, or strips, c c, (eitherhollow or otherwise,) the ends of which project beyond the ends of theroller a a,where they are provided with slots or notches d d, into which(at each end) tits loosely a ring, e e,of metal, connecting all the barscc together, so as to form a kind of cage.

In Figs. I, 2, 3, and 4 of the drawings the bars c c are shown as ovalin form and hollow and having squared solid ends for working in thegrooves, hereinafter mentioned. Outside the rings e e, at each end, is'fixed a metal disk or plate f f, Fig. 5, provided with radial grooves gg, in which the squared ends of the rods or bars c c are guided.

The rings c e are of such a diameter that when one bar c c is pressedinto its groove b l?, so as to be flush with the surface of the roller aa, (or nearly sc,) the opposite bar c c at the other side of the rollerc c is forced out by the rings e c to its fullest extent, as shown atFigs.' 2 and 4, and thus as the roller revolves the longitudinal cellsformed by the bars c c are alternately closed and opened one after theother, so as to take up the liquor and force it through the cloth.

The long strips c @,above described and illustrated, form longparallelspaces or cells from one end of the roller to the other, and ifit should be preferred to divide the whole surface into short cells, soas to prevent the liquor from escaping in a lateral direction, the thestrips or bars c c may be provided with short transverse webs ormid-feathers,(shown dotted at c' c', Fig. 1,) which Work in annularrecesses formed in the surface of the roller a c, and thus divide thelong spaces into a numberof short cells. The transverse Webs ormidfeathers on each strip or bar are (if employed) preferably soarranged as to come opposite to, the center of the space between twosimilar webs or mid-feathers upon the two strips on each side of it, soas to subdivide the cells alternately from either side.

It will be evident that the strips or bars c c IOO may be made of anythicknessor breadth,and, if sufciently broad, may be perforated, asshown in section at 7i h, Fig. 6, to facilitate the forcing out of theliquor from the spaces or recesses b Z) in which they Work, and thatthey Will act,so to speak, as plungers orsquirts to force ont the liquorfrom the said spaces or recesses through the fabric as the rollerrevolves.

I claim as my inventionl. A roller for Washing, Soaping, dyeing, andother similar machines, said roller having recesses or cells in itssurface and carrying hars adapted to he pressed into the said recessesor cells to force out the liquid through 15 the fabricas the latterpasses around the roller.

2. The combination of the roller having recesses or cells in its surfacewith longitudinal bars, a ring at each end connecting the bars, andguide-plates for the bars, substantially as 2o described.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing Witnesses.

WILLIAM BIRCH.
